Services    Application Development & Maintenance     Methodology

Application Development
Usually the WATERFALL MODEL is followed, where a systematic sequential approach to software development will be used. It starts at the systems level and progresses through analysis, design, coding, testing and maintenance. Prototyping will be used wherever necessary. The following phases are involved:

Information engineering and modeling
In this phase analysis would cover requirement gathering at the system level with a small amount of top level analysis and design, mainly at the strategic business level.

Software requirements analysis
In this phase the requirement gathering is intensified. Analysis would be conducted to understand the information domain in detail. The Systems Requirements Specifications will be documented at the end of this phase.

Systems Design
This process will translate the requirements into a representation of the software that can be assessed for quality before code generation begins. It consists mainly of systems architecture, data structures, interface representations, and procedural details. The System Design will be documented after this phase.

Code Generation
This phase includes system and procedural development.

Testing
The test phase will include internal as well external testing of the code and product. The required output should match with the actual output of the system.
